SIDE BEARING For RAILWAY-cans.

Specification of Letters Patent. Patented Nov. 2, 1920.

Application filed July 24, 1919. Serial no. 313,085.

T 0 all whom it may concern:

Be it known that I, WILLIAM H. Minna, a citizen of United States, residing at Chazy, in the county of Clinton and State of New York, have invented a certain new and useful Improvement in Side Bearings for Bailway-Cars, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in side bearings for railway cars.

()ne of the objects of my invention is to provide a body side bearing in which the anti-friction element employed shall be positively self-centering. Another object is to provide a simple and eflicient side bearing. Other objects will appear from the description of the invention hereinafter following.

In the drawings forming a part of this specification, Figure 1 is a vertical longitudinal section partly in side elevation, of a side bearing embodying my invention and shown in its position between the bolsters of a railway car. Fig. 2 is a cross section taken 011 line 22 of Fig. 1.

Referring to the drawings, the numeral 10 indicates the lower portion of the upper body bolster of a railway car. The upper portion of the lower or truck bolster is inclicated at 11. A base member 12, open at top and bottom as indicated respectively at 13 and 141, is provided with the lugs 15-15 through which it is secured to the truck bolster by suitable means, as for instance the rivets 16-16. lVithin the base member is mounted an anti-friction element 17. The anti-friction element is preferably of a general cylindrical shape and is provided at its ends with the outwardly extended guiding members 18-18. The track 20, formed in the base member at either end of the anti-friction element, forms the lower wall of a recess 21 within which a guiding member 18 is received. The said recess 21 is within the side walls 19 of the base member or end walls 22, the said end walls being sufficiently spaced apart to receive the guiding member 18 therein, with substantially little interference between the same and the said end walls, as indicated in Fig. 1 by the numerals 23-23; i. 6., the guiding members 18 substantially span the recess 21 and are each in general outline of diamond shape, so that in all positions thereof it will extend substantially across the recess 21. In the upper portion of the base member and engaging the body bolster, is mounted a filler block 2-1 of such width that it may be mounted between the guiding members 18 and underneath said filler block 2 1 a bearing plate 25 is extended, passing at its ends into the recesses 26-426, formed in the end walls of. the base member, said bearing plate and filler block being held in their position by the cotters 2727.

The anti-friction element is adapted on movement of the bolsters toward each other, to engage the lower bolster 11 which serves as the lower bearing plate as indicated at 28 in Fig. 2 of the drawing. In its normal disengaged position the anti-friction element is slightly spaced away from the hearing plate 25 as indicated by the numeral 29 in Fig. 2 of the drawing. On approach of the bolsters toward each other, the antifriction element is engaged upon its cylindrical portion between the upper bearing plate 2'5 and the lower bearing plate 28. On relative swinging movement of the bolster the anti-friction element will roll be tween the said bearing plates, and if rolled for instance toward the left, it will, on extreme movement, assume the position indi cated by the dotted lines in Fig. 1 of the drawings. In this position the guiding members 18 will be moved to the position indicated by the dotted lines, reference 30 in Fig. 1 of the drawings; On release of the anti-friction element by suppression of the bolsters, the anti-friction element will swing to its normal central position upon the pivots formed by. the diamond shaped guiding members 18 and by reason of the conformation of said guiding members, so

as to all times substantially span the re-' cess 21, the said anti-friction element will of necessity come to center upon its swinging return movement just described.

I claim:

In a side bearing for railway cars, the combination with a hollow substantially rectangular retaining member adapted to be secured to the under side of a body bolster and provided with a flat, longitudinally extending bearing surface therein near the top thereof; of an anti-friction element disposed within said member and extending.

partially below the lower edges thereof, said anti'friction element being adapted to roll. on said bearing surface but normally opposite sides thereof, each of said recesses having a horizontally extending supporting ledge at the lower end thereof, said antifriction element having a guiding member projecting from each end thereof and co6p erating with said recesses, said guiding members resting upon said ledges to thereby sustain the Weight of the anti-friction element, said guiding members being vertically movable Within said recesses and adapted also to oscillate therewithin as the anti-friction element is actuated to either 15 side from normal position, said guiding recesses preventing horizontal translation of said guiding members.

In Witness that I claim the foregoing I have hereunto subscribed my name this 21st 20 day of July, 1919.

WILLIAM H. MINER.
